Switched my '94 Rodeo to Mobil1 10w30 (5w30 lately) at 90K miles... no problems. It never burned oil before, still doesn't at 120K miles. It does leak around the valve covers.. just a little but enough to smell at shut-down... and into the sparkplug wells. But then it did that before changing, too. It never needs a top-off between changes at 4-6K mile intervals.

I've wondered if tightening the valve cover bolts would help some with the leaking.

Synthetic oil and using Fram filters has really helped keep that valve ticking noise 3.2L SOHC engines get in check.
